Padma raised an eyebrow as her sister talked, waiting for the moment when it finally hit. "Exactly. None of them know better and there are already three of us walking around with missing memories because they decided it was best." She may not remember what it was that was missing or why. But, she'd been smart enough to leave her self a reminder it was done and by whom -- one she'd replaced in a new location just in case for the future. "Their answer to information they deem dangerous is to take it away from whoever's learned it and that's even more dangerous than whatever the information was in the first place."
Rolling her eyes, she patted her sister's hand. "I don't know why he betrayed his friends, but this Peter hasn't done it, yet. Any more than a certain werewolf portrait gossip says you were rather chummy with after the Full Moon earlier this week. Whatever his future self did, Peter as he is now is very sweet. And I'm not underestimating Professor Snape. I just think that despite understanding the need to do whatever is necessary, his initial gut reaction before reason takes over will be amusing. If for no other reason that he'll still be surprised someone would actually ask him for that."
Padma sighed. "Is that really true, though? I had Hermione's memories, too. There were plenty of moments when the three of them were having fun. He had fun during the D.A. lessons. You could see it. He was focused, but he made the lessons fun, too. And what about Quidditch? He always seemed to be enjoying that. I get that his childhood was terrible. But, the other Weasleys aren't that bad and he spent plenty of time with them. How much is that he doesn't know and how much is that he chose not to have fun after the war out of some misplaced sense of duty? He could have walked away. But he's built his entire identity around that fight. He's lost sight of who he is as Harry, instead of the Boy Who Lived...Twice."
